@pibee I have read that some Lyme patients may experience paranoia symptoms. For example,
this article says:
Once inside the central nervous system, the organism can wreak all kinds of havoc, from memory problems, moodiness and depression to hallucinations, panic attacks, paranoia, manic depression, seizures and even dementia. Memory problems are the most common sign of a brain infection. When the organism invades spinal nerves, patients may develop numbness and tingling in fingers and toes and pain radiating to the front of the body.
I suffered some mild paranoia myself for a few years, as a result of my neurological virus triggering some mild psychosis symptoms (paranoia can be a sub-symptom of psychosis). Once you become aware of your own symptoms though, you can often compensate for them, or at least take them into account.
More relevant to the thread, how might a patient tease out which pathogen is a primary cause of their ME (assuming a chronic pathogen is to blame) and which ones are incidental.
If you have an active infection with any of the pathogens which researchers think can underpin ME/CFS, then those infections may well be playing a causal role. Such ME/CFS-liked infections include (roughly in decreasing order of prevalence): coxsackievirus B, echovirus, EBV, HHV-6, HHV-7, cytomegalovirus, Chlamydia pneumoniae, parvovirus B19, Giardia lamblia, Ross River virus (in Australia), Coxiella burnetii.
If you have two or more active infections with such ME/CFS-linked pathogens, then I think it is likely they are both playing a role (judging by research of Dr Lerner, who found that ME/CFS patients with such co-infections would not improve until all the ME/CFS-linked pathogens were treated with antivirals).
EDIT: actually, I am not sure about patients not improving until all the pathogens are treated, but Dr Lerner certainly would treat co-infections all at the same time, including viral co-infections (eg: active EBV + active HHV-6 treated with Valtrex and Valcyte respectively), plus treating co-infections like Borrelia, Babesia and Anaplasma. The relevant Lerner paper is
this one.
Pathogens like Mycoplasma or Brucella might worsen ME/CFS symptoms like fatigue, but are not considered causes of ME/CFS. I actually had a recurrent urinary tract / kidney infection that would flare up every few weeks, with the flare ups lasting a few days, and during each flare up, my fatigue levels would be significantly worse (but kidney infections are known to cause fatigue even in those without ME/CFS). This shows how an infection can exacerbate ME/CFS symptoms, but not be a cause of ME/CFS.
